Core i5-2450M vs Core i7-3517U comparison

In our benchmarks, the Core i7-3517U beats the Core i5-2450M in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-2450M in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Core i5-2450M has a slightly higher clock speed compared to the Core i7-3517U. Also, the Core i5-2450M has a slightly higher turbo speed. The Core i7-3517U outputs less heat than Core i5-2450M thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i5-2450M has more threads than cores. Each physical core is split into multiple threads.
